Tadalafil and analogs for bodybuilding

[Hexagon Sun]

Apart of the obvious use to get rock erections, I have read some tangential claims about PD5 inhibitors to help building muscle or improving workouts performance or similar.

Is that true? What are the mechanisms?

I believe it was posted somewhere that sildenafil (viagra) boosted natural test production but I don't think it was anything major. Does give a good pump in the gym though and can be beneficial to reduce high BP, tadalafil (cialis) mainly.
